The Three-Cylinder Dryer manufactured by Zhengzhou Zhenggang Machinery Co., Ltd. is a fully enclosed, high-efficiency industrial drying system designed for large-scale drying applications. It adopts a three-layer rotary drum structure, with the inner, middle, and outer cylinders nested together to improve heat utilization and reduce heat loss. With advanced airflow distribution and lifting plate design, the dryer ensures uniform material drying, high output, compact structure, low energy consumption, and stable operation. It is suitable for drying fly ash, slag, river sand, mineral powder, coal slime, sludge, gypsum powder, bentonite, kaolin, iron concentrate, steel slag, and other granular, powder, or block materials.
The three-layer rotary drum structure improves heat utilization, reduces heat loss, and supports efficient drying performance.
Designed for continuous industrial drying, the dryer provides high throughput for fly ash, slag, river sand, and mineral powder.
The system reduces coal and power consumption compared with traditional single-cylinder dryers, helping lower operating costs.
The three-cylinder design reduces floor space and foundation investment, making it suitable for space-saving plant layouts.
Suitable for materials with different moisture levels and flowability, including granular, powder, and block materials.
The sealed structure helps prevent air leakage, supports cleaner operation, and improves environmental performance.

Suitable for drying river sand and sea sand for dry-mix mortar, construction materials, and sand processing plants.

Used for drying steel slag, water slag, and industrial slag powder before grinding, storage, or further processing.

Designed for efficient drying of fly ash in cement, building materials, and industrial powder production lines.

Suitable for drying iron concentrate, copper concentrate, lead concentrate, fluorite ore, gypsum powder, bentonite, kaolin, and other mineral materials.

Applicable for high-moisture materials such as coal slime, sludge, petroleum coke, and similar industrial materials.

Used in dry-mix mortar plants for drying river sand, yellow sand, slag, fly ash, and mineral powder, helping produce low-moisture materials for construction mortar and building material production.
